Year: 2024
Type: article
Abstract: In this study, a new salt {(H2BPE)(PDA), 1} synthesized from 4,4’-ethylenedipyridine (BPE) with 2,3 pyrazinedicarboxylic acid (H2PDA) and its complexes Fe(III) {(H2BPE)[Fe2(PDA)(H2O)4]n, 2} and Ni(II) {[Ni(PDA)(BPE)2(H2O)2]n.H2O, 3}, were synthesized and defined by using 1H and 13C NMR, TG-DTA, IR, UV Vis, elemental analysis, magnetic susceptibility techniques. In addition, antibacterial and antifungal activities of starting materials and synthesized compounds against Candida albicans yeast and Bacillus subtilis, Staphylococcus aureus, Enterococcus faecalis, Pseudomonas aeruginosa, Escherichia coli and Listeria monocytogenes bacteria were investigated using the microdilution method and compared with existing antibiotics (Cefepime, Vancomycin, Levofloxacin and Fluconazole). Compounds 1-3 were observed to have activity against yeast and bacteria. In particular, compound 3 (7.80 µg/mL) against E. faecalis, compounds 3 (7.80 µg/mL) against B. subtilis bacteria, and compound 1 (15.60 µg/mL) against C. albicans yeast. showed better activity than control compounds.
